					What’s MAX Production Been Up to?
Presentation to MAX membership

Fall 07 Member Meeting


 Dan Magorian
  Director of
 Engineering &
  Operations
 What has the Production Side of MAX been
  doing since the Spring member meeting?
• The last 6 months has been one of the biggest network
  changeovers in MAX’s history! (“The Big Move”)
   –   We interviewed many potential dwdm system vendors.
   –   Did a pseudo-RFP process with UMD procurement helping.
   –   Worked with our technical advisory committee (TAC, thanks guys!)
   –   Took field trips to the short-list vendors sites for lab testing.
   –   Selected a vendor (Fujitsu Flashwave 7500).
   –   Got the PO expedited through UMD Purchasing in record time.
   –   Got delivery expedited through Fuijitsu.
   –   Installed in MAX lab, configured, and out to field in one month.
   –   Inc lot of prep, ripping out Movaz dwdm systems, customer
       coordination, and cutover in 3 main pops.
• Phase 1 of Fujitsu Flashwave 7500 system has been
  selected, procured, and installed in record time!!
Example: Baltimore DWDM installation timetable as of July.
    Slipped about a month, was still very aggressive.

•   7/27 Parts arrived, breakers changed, Fujitsu 7500 PO cut.
•   8/3 Norwin and DaveI move Force10, install MRV 10G
•   8/3 Dan and MAX folks have 10G lambda Mclean ready
•   8/10 Dan and MAX engineers at Fujitsu training TX
•   8/17 Balt peerings moved to Force10s/T640s
•   8/17 Bookham filters arrived, Aegis power mons installed.
•   8/24 M40e, Dell, 6 SP colo rack 3 cleared.
•   8/24 (depends on Fujitsu ship) Fujitsu gear staged in lab
•   8/31 Fujitsu DWDM and switch installed in colo rack 3
•   9/7-14 Move participant peerings to lambdas on Bookhams
•   9/21 Mop up of Aegis power monitor mrtgs, etc
            Where are we today vs April?
  3 main pops in Mclean (LVL3), College Park, and 6 St
  Paul Baltimore almost complete.
• This included a major move of our main UMD pop:
   –   into the NWMD colo area of UMD bldg 224 room 0302
   –   moving out of OIT colo area of UMD 224 room 0312.
   –   involved renovating the racks, moving over MD DHMH gear
   –   tie fibers, unfortunately coupled with huge fiber contractor hassles
   –   NWMD folks (Greg and Tim) were very helpful.
• Still to be done:
   – tie fiber in 6 St Paul (do it ourselves next week with our new
     Sumitomo bulk fusion splicer)
   – Finish up of BERnet dwdm filter cutovers
   – Phase 2 dwdm, replacing ancient 2000 Luxn dwdm DC ring.
• Very proud that we moved all the customer and backbone
  lambdas with only tiny amounts of downtime for the cuts!
• Especially want to thank Quang, Dave, Matt, and Chris!
In addition to the dwdm changeover, the other pop
    moves have been a huge piece of work also
• In Mclean, had to move the HOPI rack to Internet2’s suite
• In Baltimore, we’re sharing USM’s Force10 switches, and
  removed the BERnet Juniper M40e. Lot of cutover work.
• Moved the NGIX/E east coast Fednet peer point
   –   Procured, tested in lab, and installed in new CLPK pop.
   –   Including a lot of RMA problems with 10G ints.
   –   Lot of jumper work, config moves and night cuts to get done.
   –   Monday just moved out CLPK Dell customers.
   –   Next up: moving the lab T640 to the new CLPK pop, new jumpers,
       config move and consolidation.
• We had intended to have new dense 1U Force10 or
  Foundry switches selected and installed
   – But found that their OSes were immature/unstable.
   – Had to do an initial one in Equinix pop to support new 10G link.
   – So made decision to consolidate onto Cisco 6509s for Phase 1,
     postpone Phase 2 switches till spring 08.
RR402 Before: 48V PDUs, Dell switch and inverters, Force10 (top), Juniper M40e (bot)
RR402 After: Fujitsu ROADM optical
shelf (top), transponder 1-16 shelf (bot)
with 2 10G lambdas installed, Cisco 2811
“out-of-band” DCC router with console
cables, Fujitsu XG2000 “color translator”
XFP switch. Still to be installed:
transponder 17-32 shelf to hold space.
RR202 after: Force10 E300 relocated
(top, still needs to be moved up), 3
Bookham 40ch filters, Aegis dwdm
power monitor, tie fiber panel to RR402

          Next Steps for the Big Move
• NGIX 6509 chassis just freed up moves next week to
  MCLN installation with connecting 10G lambda. This is the
  start of MAX’s Layer 2 service offering.
• USM finishing optical work on 660-6SP MRV dwdm link.
• Will put in BALT production 10G to MCLN, allows protected
  double peerings with MAX T640s.
• 40 channel filter installs: 6 SP/660 RW ends in (except
  Sailor), need to install/test participant ends, transition fibers
  from 1310 to dwdm: 660-6SP, JHU/JHMI, UMBC, Sailor,
  Morgan. Also Pat Gary’s group at CLPK. Then bring up
  sfp/xfp lambdas on, set up Aegis power mons /web pages.
• Move of CLPK Juniper T640 to new pop next: big one.
• Hope to have all pops move done by end of Dec/early Jan.
  Happy to give tours!
                Phase 2 of dwdm system

• In spring will continue to unify new Fujitsu dwdm system.
• Ironic:
    –   Phase 2 is replacing our original Luxn/Zhone system from 2000
    –   While Phase 1 was replacing the Movaz/Advas that came later.
    –   Those reversed due to the need to get main Ring 2 changed first.
    –   So now we’re moving on to change over the original ring 1.
    –   Luxn/Zhone dwdm now completely obsolete, really unsupported.
• Still an issue with less traffic to DC. One 10G will hold L3
  traffic to participants for awhile.
   – Very interested in hearing/collaborating on DC lambda needs.
   – There is an initiative with the Quilt for low-cost lambdas, which
     we’re hoping will result in Qwest offering to MAX and rest of
     community, feed lambdas from original DC Qwest pop.
• Get involved with TAC to hear details: tac@maxgigapop.net

  RFC2547 VRFs (separate routing tables)
    expansion gives participants choice
• Due to Internet2 and NLR merger not happening,
  converged network does not appear in the cards.
• This means business as usual: I2 and NLR acting as
  competitors dividing community, trying to pull RONs to
  “their” side, increasingly acrimonious.
• We intend to do our best to handle this for folks (to the
  extent possible) by playing in both camps, and offering
  participants choice.
• So have traded with VT/MATP for NLR layer 3 PacketNet
  connection, in addition to (not replacing) I2 connection.
• Technically, have implemented this on Juniper T640
  routers as additional “VRFs”: separate routing tables
  which we can move participant connections into.
• Dave Diller is “chief VRF wrangler”, did tricky “blend” work.
MAX has run VRFs for years, now has 5

      Participant Peering Vlans
              New Service: Layer 2 vlans

• Announced in Spring member meeting.
• MAX has traditionally run Layer 1 (optical) and Layer 3
  (routed IP) service.
   – Only NGIX/E exchange point is Layer 2 service.
   – Continues to be demand for non-routed L2 service (vlans), similar
     to NLR’s FrameNet service.
• This means that folks will be able to stretch private vlans
  from DC to Mclean to Baltimore over shared 10G channel.
• Also will be able to provision dedicated ethernets.
• Next week we’re moving Cisco 6509 out to Mclean early to
  get this started, will interconnect two main switches with
  10G lambda.
• Haven’t figured out service costs yet, will involve TAC.
• Your ideas and feedback are welcome.

             New service: Flow analysis
• We announced this in the spring. Turns out it would be
  useful to be able to characterize traffic flows passing thru
  MAX infrastructure for participant use.
   – We bought Juniper hardware assists and big Linux pc with lots of
     disk to crunch and store a year’s data.
   – Using open-source Flow Tools analysis packages.
• Not snooping packets: contents not collected by Netflow, but
  does have source/destination addresses and ports. So
  there are some confidentiality issues, not anonymous yet.
• Have done a prototype for people to look at. Send email to
  noc@maxgigapop.net for url and login/password if you’re
  interested in testing.
• Ideally, would like web interface where people put in AS #s
   – Then could look at flows to/from their institutions
   – Could also look at protocol (traffic type), top talkers, etc.
• Interested in people’s ideas and feedback during afternoon.

                  Peering Services

• There has been some interest in either Internet2’s
  Commercial Peering Service and/or Cenic’s TransitRail.
• Right now, we offer Cogent at $16/mb/m through GWU and
  Qwest for $28/mb/m, soon to drop several $/mb/m based on
  Quilt contracts. Demand for Cogent has been slow.
• Have been thinking about mixing one or both peering
  services in with the Cogent offering, might enable us to drop
  price to around $10/mb/m, depending on traffic mix.
• Problem is, demand has to be enough to cover the “peering
  club” and additional infrastructure costs. We tried this long
  ago with direct Cogent connection, not enough folks signed.
• Would people be interested in this? Hope to hear
  discussion and feedback in the afternoon sessions.
    Closing thought: the new Fujitsu dwdm
        system is part of a sea change
• Not just needed to create a unified infrastructure across MAX region
  and replacing aging vendor hardware.
• Also lays foundation for dynamic circuit and lambda services activities
  that are happening in the community
• Want to get people thinking about implications of dynamic allocation,
  dedicated rather than shared resources:
    – Circuit-like services for high-bandwidth low-latency projects
    – Not replacement of “regular” ip routing, but in addition
    – Possible campus strategies for fanout. Need to plan for how will deliver,
      just as BERnet doing
    – facilitating researcher use of this as it comes about.
• People may say, “We don’t have any of those applications
  on our campus yet”.
    – But suddenly may have researchers with check in hand
    – Eg, in planning phase now for DC ring, need to forecast.
    – Talk to us about what you’re doing and thinking!
       Thanks!
